Bug 380500

The ksmserver crashes, both restarting and shutting down. Note that I'm coming form a "suspend to ram" state and the system made an update regarding Nvidia driver (no restart made).

Application: ksmserver-logout-greeter (ksmserver-logout-greeter), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
